In this research, the fundamental research was accomplished for a development of rolling bearings with 10 nm level in non-repetitive run-out. The results are summarized as follows ;(1)The non repetitive run-out(NRRO) value of the components of cage rotation is mainly caused by the diameter differences of balls contained in one bearing. But in case of measuring NRRO for a long time, it was often observed that the NRRO of retainer rotation fluctuated suddenly. As for this phenomenon, geometric errors were not regarded as a cause. In this research, we produced the instrument which could let a lubrication state change intentionally and investigated the influence of lubrication fluctuation on the NRRO of retainer rotation. It was cleared that the lubrication fluctuation was the cause of the change of the NRRO of retainer rotation in nm level.(2)The NRRO of rotational frequency of the cage is mainly caused by the diameter differences of balls contained in one bearing. In addition, it was kno … More wn that the unequal orbital intervals of balls could influence the NRRO of rotational frequency of the cage. But there were few quantitative studies about this. In this research, we investigated the influence of the unequal orbital intervals of balls on the NRRO of retainer rotation by pulling out balls intentionally. It was clarified that the NRRO of rotational frequency of the cage became large if the difference between orbital intervals of balls was large.(3)The NRRO value of retainer revolution is caused mainly by the diameter differences of balls mounted in a bearing. Additionally, when more than one ball has diameter difference, the NRRO value of retainer revolution is believed to vary with the location of balls. In this research, we theoretically analyzed the NRRO value of retainer revolution considering the diameter differences and location of balls mounted in a bearing. Consequently, it is clarified that the mean value of the retainer revolution component calculated in all locations of balls decreased with increasing number of balls in a rolling bearing. Less

在这项研究中，基本研究是为开发滚动轴承而在非重复竞争中的滚动轴承水平的开发而完成的。结果总结如下;（1）笼旋旋的成分的非重复跳动（NRRO）值主要是由一个轴承中包含的球的直径差异引起的。但是，在长期测量NRRO的情况下，经常观察到固定器旋转的NRRO突然波动。至于这种现象，几何误差不被视为原因。在这项研究中，我们生产了该仪器，该仪器可以使润滑状态有意变化，并研究了润滑波动对固定旋转NRRO的影响。可以清楚地看出，润滑波动是NM水平固定旋转NRRO的变化的原因。（2）笼子的旋转频率的NRRO主要是由一个轴承中包含的球直径差异引起的。此外，这是kno…更多的是，球的不等轨道间隔可能会影响笼子旋转频率的NRRO。但是关于此的定量研究很少。在这项研究中，我们通过故意拉出球来调查球的不等轨道间隔对固定器旋转的NRRO的影响。可以澄清的是，如果球轨道间隔之间的差异很大，笼子的旋转频率的NRRO变大。（3）保留革命的NRRO值主要是由安装在轴承中的球直径差异引起的。此外，当多个球具有直径差时，据信，固定器革命的NRRO值随球的位置而变化。在这项研究中，考虑到安装在轴承中的球的直径差异和位置，我们从理论上分析了保留革命的NRRO值。因此，可以澄清的是，在所有球的所有位置中计算出的固定器革命组分的平均值随滚动轴承中的球数量的增加而降低。较少的
